DEVOPS TEAM ON DEMAND

We help tech companies scale engineering capacity and deliver perfect systems

PROCESS ASSISTANCE

We gratefully respect the business process teams can have and are ready to give you our support combining all the benefits of Cloud solutions, without compromising the way everyday business runs in your company. As a tech company you need to manage source code, build and delivery it to the cloud.

Our custom Serverless solutions allow you to manage all the tasks in a cloud and do sales via a Serverless CRM system, and because this is Serverless, you only ever pay for what you use.

DATA ANALYTICS

Nowadays Data is the fuel of global Economics, so we must respect the way in which we understand and use it. With proper usage of your data, it can become a powerful tool to set your company apart against others.

AWARENESS

We call it awareness because as a business owner you have to be aware of all the risks and bottleneck in your systems. Having all the required skills to do security and resilience audits our mission is to make our awareness super clear.

SERVERLESS

Yes, Serverless is about costs. Have an idea? Ready to do a Proof-of-Concept? But don’t have a big budget - then Serverless is definitely the choice for you. If your business relies on “pay as you go” charges for the customer - then Serverless is your choice. Need resilience, security and scalability out of the box – once again, Serverless is your choice.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

I am the Founder and CEO of Audience Genomics... Moneyball for Content. We deliver data to support content creation and distribution decisions which, up until now, were made purely by gut. Our data is tailored to help storytellers to understand the interests, attributes and values their target audience responds to.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Perfsys?

We hired Perfsys to develop a complex Extract Transform and Load project

What were your goals for this project?

Our goal was to be able to dynamically assign descriptions, labels and categories to people places and things.

SOLUTION

How did you select this vendor?

Perfsys came highly recommended by an existing client.

Describe the project and the services they provided in detail.

Perfsys built a serverless architecture system that allows us to quickly and cost-effectively search terabytes of data, find the relevant record, extract the relevant values from the record and append the information to our database. They also built a front end user permissioning system.

What was the team composition?

The team consisted of two dedicated developers and the company's principal who provided hands-on strategic direction.

RESULTS & FEEDBACK

Can you share any information that demonstrates the impact that this project has had on your business?

The work that Perfsys delivered replaces manually work that would have previously taken hundreds of man-hours. We now have a system that can scale and handle any demand in just minutes.

How was project management arranged and how effective was it?

We worked in two week sprints, communicated multiple times a day over Slack and the team was available to join us for phone calls and/or videoconferencing with screen shares whenever it was needed. The project management was highly effective.

What did you find most impressive about this company?

What was most impressive was their strategic thinking. The team was far from one that just followed direction blindly. They truly took ownership over the project and they gave it the same level of thoughtfulness, care and attention to detail as if it were their own software.

There is very little I would recommend as areas for improvement.

Feedback summary: 

Reliable and consistent, Perfsys offers a solid cost-effective maintenance package with built-in alerts. The team is proactive in resolving website errors, ensuring users experience few to no issues. Although they can improve bespoke development, they are trustworthy and provide candid feedback.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

I am the CTO of Intro, Inc.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Perfsys?

We hired Perfsys to create a serverless website and a CodePipeline for building and deploying sources. 

What were your goals for this project?

 The goal was a cloud-based website that met our requirements. 

SOLUTION

How did you select this vendor?

We selected them based on recommendations from our partners.

Describe the project in detail.

They built the website using AWS S3 and AWS CloudFront. The project also required experience in Python, API Gateway, and AWS Lambda. 

What was the team composition?

They provided one full-time Python developer, one full-time Javascript frontend developer, and one development operations manager. 

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

I trust them. I can go to bed at night and know that I will not wake up in the morning to a user complaint about website or login errors, something I experienced on a weekly basis with my previous agency. I have a very high level of confidence with Perfsys. Their maintenance package includes built-in alerts, none of which have been triggered yet. If something were to go wrong on the Perfsys side, I am confident they will know about it and resolve it before I hear of it from a user. 

How effective was the workflow between your team and theirs?

Their development workflow was based on the Agile/SCRUM approach. We had daily sync calls as well as weekly planning meetings.

What did you find most impressive about this company?

Although we may suggest an idea, they will always keep us straight on industry best practices. The maintenance package I pay now is less than the retainer I for the previous agency, who regularly complained that the retainer was not enough to cover the number of hours they worked each month.  

Are there any areas for improvement?

They need to be more proactive in creating bespoke elements on the website and in suggesting better enhancements.

Perfsys provided full-stack development using technologies such as Node.js, Docker, NoSQL, Hadoop, and Ext JS.

We successfully built and deployed the product to production environments, and were able to gain business from the scalability and ease of configuration that the solution offers.

How was project management arranged and how effective was it?

The project was managed by an internal project manager. We used Google Hangouts, Mind Maps, and internal sprint management tools.

What did you find most impressive about this company?

Their ability to meet a deadline and implement complex solutions with little rework is remarkable.

None that I can remember.
